SPECIFICATION forming part of Letters Patent No. 735,675, dated August 4, 1903.

Application filed January 19, 1903. Serial No. 139,693. (No model.)

ence being had to the accompanying drawings, which form a part of this specification.

Our invention relates to motors employingelastic fluid; and it consists in the improvements hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side view of an engine embodying our invention,the upper part being broken away to economize space. Fig. 2 isan elevation of one end of the same looking from the left of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 6, except that the port f, which comes back of the plane of section, is shown in full section in the figure. Fig. 4 is a detail sectional view of the rotary valve used in the forward motion of the engine. Fig. 5 is a sectional detail view of the rotary valve used when the engine is reversed. Fig. 6 is a section on the line 6 6 of Fig. 3. Fig. 7 is a perspective view of one of the rotary valves. Fig. 8 is a plan view of a spider used to support the valve-stem. Fig. 9 is a detail view showing a section on the line 9 9 of Fig. '6.

A indicates a casing which is steam tight and within which are contained the cylinders and valve-casings and all the motor parts except the principal lever, which turns the throttle-valve and simultaneously shifts into -tion.

cated at diverging angles of one hundred and thirty degrees. In the angular space between two of the cylinders F F is located a cy1inwill be hereinafter explained.

drical valve-casing D, the axis of which is parallel with the axis .of the shaft A The casing I) has a communicating pipe f, which leads from it to the closed end of the cylinder F and furnishes a communicating passage between the valve-chamber in the casing D and the chamber behind the piston in the cylinder. F. A similar pipe f leads from the casing D to the head of the cylinder F and furnishes a communicating passage between the valve-chamber within the casing D and the cylinder-chamber behind the piston in the cylinder F. A similar pipe f leads from the casing D to the cylinder F 2 and furnishes a communicating passage between the chamber within the casin g D and the chamber behind the piston in the cylinder F The several pistons in the cylinders F F F are provided with connecting-rods f f and f which connect with the single crank-pin a on a crank-disk A The shaft from the disk A protrudes through one face of the casing A, and it is strongly supported within the casing by a long bearing on bracket A Within the valve-casing D are two rotary valves D and D arranged to be shifted, as These valves D and D are similar except that they are set the one for direct and the other for reverse action. Both turn in the casing on a single shaft D which is itself hollow for a purpose hereinafter specified.

Into oneend of the hollow shaft D is inserted a rod D, that projects through stuffing-boxes through the shell of the casing A,

and at its terminus has pivotally connected to .it a pressurecam E, hereinafter more fully explained. The stem D is feathered concentrically to a gearwheel G and the gearwheel G is j ournaled in the shell of the casing A. The gear-wheel meshes with an idler G, journaled on a stud secured to the casing A, and the idler meshes with a driving-wheel G, that is keyedto the shaft A. The shaft A and the shaft D turn with equal speed. On the shaft D are the two valves D and D and of these the valve D is provided with passages which register in regular rotation with the passages f f f and with a groove which registers in regular succession with the same passages ff f For example, steam entering through the inlet and passage 0 is admitted to the valve-chamber, and when the valve is in the position shown in Fig. at is admitted to the passage f, and thence passes to the rear of the piston in the cylinder F. In the position shown in Figs. 3 and 4c the valve is just about to cut off to the passage through the pipe f and just about to open the passage through the pipe f. At this time the piston in the cylinder f is making its back stroke. The most of the actuating-steam has escaped from the cylinder through the outlet 11 but there is a residuum which is at low pressure or at atmospheric pressure, and this residuum is pushed back by the piston through the passage of the pipe f and escapes through the groove D (seen in Fig. 6) through the passage D which is bored radially into the axial passage 1)" in the stem D and this residual escapes through the end of the stem and to the outer air. The main exhaust which has escaped through the opening Il passes into the chamber within the case A and thence through the exhaust-pipe C. (Seen in Fig. 3.) The valve D is arranged for direct rotation and for direct actuation of the pistons. By shifting the valves to bring the valve Dint'o opposition to the various passages through the pipes fff the engines are reversed, the valves are shifted by the rod D, which does not rotate, but which is held by a collar connection to the hollow shaft D and extends through the casing and is pivoted to a shiftcam E. The shift-cam E is a cross-bar arched concentric with the shaft Band supported by sleeved ends 6 and (2 upon posts E and E that project from the face-plate of the casing A. On the posts between the casing and the sleeves are springs e and 6 that hold the sleeves toward the outer end of the posts E and E There is secured to the protruding end B of the throttle lever B a lever D, which reaches over the diagonal cam E and swings in contact with the outer side thereof. The contact is made by a friction-roll (Z, j ournaled in the lever D. The combined action of the swinging lever and the springs a and 6 acto ate the sleeves e and e and the cross-bar E, which connects them, and this in turn actuates the stem D, which shifts the valves D and D The leverD also aetuates the throttlelever B simultaneously with the shifting of the valves D and D The throttle B is arranged to open and close the inlet-passage C. It is a hollow conical plug having two pairs of opposite openings. (Shown in Fig. 9.) \Vhen the lever D is swung to press the crossbar inward toward the casing A, it forces the rod D inward and brings the valve D into register with the several passages, and at the same time it opens the throttle B to give free passage to steam through the passage 0. \Vhen the lever is swung in the opposite direction, the springs force the cam-bar E outward, and this carries the rod D and shifts the valve D into register with the passages; but this valve is timed with respect to the engine to produce a reverse action of the several pistons from that which is produced by admission of steam through the valve D During the time of movement of the valves D and D, after D has passed out of register with the passages and before D has arrived in a position of register with the passages, the throttle is in position to prevent the passage of steam through the passages O entirely.

The valves D" and D are each made as a split cylinder and bear with an expansive spring action against the shell in which they rotate, the ends I I of the cylinder bearing against the inner walls, and the spring action is assisted by weakening the walls of the valve somewhat by grooves i and by the use of coiled spring 21, inserted between the parts I I and the hub of the valve.
